A robust algorithm for automatic target recognition using passive radar

Thirty-Sixth Southeastern Symposium on System Theory, 2004. Proceedings of the, 2004
The goal of this research is to add automatic target recognition (ATR) capabilities to existing passive radar systems. We do so by comparing the radar cross section (RCS) of detected targets to the precomputed RCS of known targets in the target class. The precomputed RCS of the targets comprising the target class is modeled using a multi-step process ...

Enhanced synthetic aperture radar automatic target recognition method based on novel features

Applied Optics, 2016
This paper proposes a set of uncommonly rich feature representations for automatic target recognition (ATR) in synthetic aperture radar (SAR) images. The proposed novel feature representations capture both the spatial and spectral properties of a target in a unified framework, while simultaneously offering discrimination and robustness to aspect ...

Using the Amplitude Fluctuation Property of Target HRRP for Radar Automatic Target Recognition

2006 CIE International Conference on Radar, 2006
Due to the aspect sensitivity of high-resolution range profile (HRRP), traditional radar HRRP target recognition methods usually use average profile within some target-aspect region as the target-aspect template. Actually, the amplitude fluctuation property of target HRRP also represents some feature information of the target.

Exploitation of target shadows in synthetic aperture radar imagery for automatic target recognition

SPIE Proceedings, 2006
The utility of target shadows for automatic target recognition (ATR) in synthetic aperture radar (SAR) imagery is investigated. Although target shadow, when available, is not a powerful target discriminating feature, it can effectively increase the overall accuracy of the target classification when it is combined with other target discriminating ...

An overview of radar-based, automatic, noncooperative target recognition techniques

IEEE International Conference on Systems Engineering, 1991
Radar target recognition techniques tend to fall into two principle classes: those that exploit the radar characterization of a platform's physical shape and those that exploit the radar characterization of the dynamic characteristics of the moving parts of the target.

(Automatic) target detection in synthetic aperture radar imagery via terrain recognition

Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
Surveillance of large areas of the Earth's surface is often undertaken with low resolution synthetic aperture radar (SAR) imagery from either a satellite or a plane. There is a need to process these images with automatic target detection (ATD) algorithms.

Automatic target recognition using waveform diversity in radar sensor networks

Pattern Recognition Letters, 2008
In this paper, we perform a number of theoretical studies on constant frequency (CF) pulse waveform design and diversity in radar sensor networks (RSN): (1) the conditions for waveform co-existence, (2) interferences among waveforms in RSN, (3) waveform diversity combining in RSN. As an application example, we apply the waveform design and diversity to

Radar Sensor Networks for Automatic Target Recognition with Delay-Doppler Uncertainty

MILCOM 2006, 2006
Automatic target recognition (ATR) in target search phase is very challenging because the target range and mobility are not yet perfectly known, which results in delay-doppler uncertainty. In this paper, we firstly perform some theoretical studies on radar sensor network (RSN) design based linear frequency modulation (LFM) waveform: (1) the conditions ...
